以2012年从乌兹别克斯坦引进的一年生豆科饲用植物猪屎豆(Crotalaria alata)为研究对象,2013年和2014年分别在新疆呼图壁和阜康进行了引种试验,对该牧草适应性及农艺性状进行了观测与评价。结果表明,饲用豆科植物猪屎豆在新疆呼图壁、阜康平原区生长发育良好,根部能发生固氮根瘤,株高可达180 cm。初花期粗蛋白质含量最高,可达23.02%,粗纤维含量20.3%。该植物营养丰富,含有17种氨基酸。呼图壁和阜康两处平均鲜草产量分别为23 833.5、21 750.0 kg·hm-2,种子产量分别为366、385.3 kg·hm-2。综合评价认为,引种的猪屎豆适合在新疆北部平原区种植推广。
The annual leguminous plant Crotalaria alata, introduced from Uzbekistan in 2012, was studied. In 2013 and 2014, the introduction experiments were conducted in Hutubi and Fukang of Xinjiang respectively. The adaptability and Agronomic traits were observed and evaluated. The results showed that the legume beans of fodder legume grew well in Hutubi, Fukang Plain of Xinjiang and had nitrogen-fixing nodules at the root, with the height of 180 cm. The initial crude protein content of the highest, up to 23.02%, crude fiber content of 20.3%. The plant is nutritious and contains 17 amino acids. The average yields of fresh grass in Hutubi and Fukang were 23 833.5 and 21 750.0 kg · hm-2, respectively, and the seed yields were 366 and 385.3 kg · hm-2, respectively. Comprehensive evaluation that the introduction of pig crud bean suitable for planting in northern plains promote.
